Use of a specially developed frequency converter offers tremendous advantages. The most important features are variability in speed, resistance against voltage and frequency fluctuations, no current peaks during start-up as well as gentle operation of the valve by reducing speed in end positions. The robust design is extremely resilient against environmental influences (standard corrosivity class C5, IP67, double sealed – protection is also ensured during commissioning) and can be further enhanced as an option. 

With SAV .2 multi-turn actuators for open-close duty and SARV .2 for modulating duty paired with ACV .2 actuator controls, the proven AUMA SA/SAR range is enhanced by variable speed models. AUMA is spearheading market technology offering a wide speed control ratio of 1:10.
Actuators of the SAV type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min. A special version for longer running is available for the S2 - 30 min duty.
Actuators of the SARV type range are rated for class C or types of duty S4 - 25 %. Special versions for S4 - 50 % are also available.

Actuators of the SA type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min. A special version for longer running is available for the S2 - 30 min duty.

The modulating actuators of the SAR range are rated for class C or types of duty S4 - 25 %. Special versions for S4 - 50 % and S5 - 25 % are also available.

Actuators of type range SA/SAR can be combined with various controls from simple OPEN-CLOSE control to the micro-controlled version with logging of operating data or fieldbus interface 

The TIGRON is a multi-turn actuator with classic mission:
Automation of gate valves with or without rising stem as well as double block and bleed valves.
Virtually unlimited stroke
Rising stems are lead through the multi-turn actuator hollow shaft driving the stem thread. The stem protection tube protects the stem from pollution and people from injuries.
Open-close and modulating duty
TIGRON actuators versions are available for both types of duty.
Combinations with multi-turn gearboxes
In combination with GK or GST gearboxes, torques up to 16,000 Nm can be reached.
